Quite the opposite oddly enough , higher quality scopes dont tend to work well with add on NV due to lens coatings, plus do you want a NV unit that close to your eye ? , I`ve never liked add on`s , buy a dedicated unit.
Buy a Photon and be very happy.
The bottom line being any doctor/hearing specialist will tell you to wear defenders even with a moderator on most calibres and when you get to the bigger stuff like 300WM and above you should wear ear plugs and ear defenders , and as we all know no moderator can get rid of the super sonic crack so there's not much to argue about regarding dB reduction if you are wearing defenders when using a mod.
The only time you want the best moderator is when you use subsonic ammo or you storm embassy`s for a living.
I`ve never found the need for a moderator that does more the reduce noise to a level you do not need ear defenders when stalking/hunting in open spaces , we all wear defenders at the range and confined spaces , I suppose theres a " Walting " value to some.
You`ll have to try harder if you are going bluff people on the net...
You've really made a fool of yourself ,if you`d come onto the site and been honest about your motives and told the truth about your products I`m sure you would have received a warm reception .
From the Perkin website "We are custom knives makers based in UK. But our most knives smith based Outside UK and we do not produce knives in UK." ,all very confusing .
